' To ail whom it may concern:

Be it known that I, EDWARD R. Benirsrr, a citizen of 'the United States, residing at Detroit, in the county of Wayne and State f l\lichiga n, have invented certain new and useful Improvements Adding and List Mmihinee of which the following is a specification.

The present invention relates to the equipment of an adding and listing machine for doing what is commonly-termed split work. which meansmulticolumn work with the paper in one position so far as its lat eral adjustment is concerned Grdinarily the so called splitting an adding machine is accomplished by ..er-- rupting or suspendin,- the cooperative action between elements of the printing mechanism. The commonest form of printing mechanism for these machines is that wherein are normally retracted ar aiiist spring pressure and the latches ch hold 5 back are adapted to trip ne: another ior the purpose of filling in vi, a

hive cipher keys and the cipher types are I brought automatically to the printing position in all numerical orders and in any orders to the right of the highest digit of the amount being registered-and recorded, wherein no digits occur, the ciphers are printed as a result of the tripping of the hammer latch of some order to the left wherein a digit is printed; It is new a well known expedient, for the purposes of the so called splitting, to provide movable couthat to any extent desired asto location or number of splits or points of interruption. without relying upon any special construc tion of the printing or recording section or department of'the machine by which I mean .the mechanism for making the impressions.

I propose to accomplish the result primarily through a control of the setting of; type carriers to present ciphers at the printing .ers. These machines ordinarily do -not.

then by tionally arrai crevices be modified so the res l. of depressing an amount key representing the first digit of an amount to be recorded will unlatch the associated type carrier and a series of type carriers to right up to a certain predetermined point. The result is that automatic sett g of cipher types will thereafter'occur only throughout the predeterf denominacondition can mined range, and separate items may be printed in one or more parallel vertical columns without.

The numeral 291 designates the usual amount keys which operate in the familiar manner to set stops for limiting the descent of the segmental racks 610. 'lhe latter are mounted as usual upon the front ends of levers 611 through a sl t-pin-spring connection to permit one-step movement of any rack relative to its supporting lever and vice versa. Levers 611 carry the usual type plate 618 their rear ends for striking against a roller platen 3 under actuation by hammers 715. Hammer latches or detents 717 normally restrain the hammers as usual, and pawls 718 individually trip said latches provided associated levers 611 have moved far enough to present digital types at the printing line; otherwise tails of the pawls encounter shoulders of the levers and the pawls are rocked thereby so as to miss the latches. The latter however have the usual overlapping tails so that one may trip an-x other from left to right throughout theseries. All of this is old and well known and it need merely be noted at this point that in the normal position of the type carriers the uppermost types, which are the cipher types, are below the printing line and the plates carrying these types are below the paths of movement of the hammer heads so that releaseand discharge of hammers with the type carriers so held would not resuit in any printing. I mention this here because in carrying-out my invention, 1 take advantage of this condition to prevent the printing of ciphers beyond the point of split. The first thing to be noted as to change in form of familiar parts of this machine is that each of the levers 611 near its ront end is formed with an upstanding arm lill having the character of a hook in that its upper extremity is undercut at the rear. Upon one of the cross rods 200 under the keyboard which ordinarily supports the key operated bell cranks 217, there are loosely hung depending pawls 10, one for each hook 611 (see Fig. 9), the laterally turned terminal portions or feet of these pawls being adapted to engage said hooks for the purpose of blocking the usual one-step move- Inent of the levers-611, which movement ould result in bringing the cipher types to the printing line. Ptearwardly extending upper arms 10" of these pawls carry roller studs 10 which are adapted to he acted upon by substantially i -shaped cam portions 13 of disks 13 secured to a rock shaft 200 which the right of the machine carries a han die is projecting through slot 02? keyboard (Fig. 8), alongside an index. plate 18 inscribed Nor at one place and Split a space in rear thereof. With. the handle forward opposite the inscription Nor the pawls 10 are all rearward as illustrated in Fig. 2, whereas the result of throwing the handle back to register with the inscription Split is to cause the cam projections 13 to operate upon the roller studs 10 and throw all of the pawls 10 forward so as to engage their feet 10 with the hooks 611. as illustrated in 3. It will be seen by reference to Fig. 3 that when the handle 14.- has been so thrown rearward, the cam projec tions 13 will have passed so far orward ot the studs that, in the absence of restraining means, the pawls 10 would immediately swing back to normal under the action of their retracting springs 11. However the pawls are caught and held in their forward position by special latching devices, one of which appears in perspective in 7. Theseare in the form of yolres or hails strung on a cross rod 200* and tending by gravity to assume positions such sin vn in Fig. 5 wherein they latch the pawls it) in their .forward position. l lornially these latching yokes or bails are swung upw and rearward as shown iii Fig. 3, being so held by the pawls themselves. The construction of all of them is the same so that a detailed description of: one will sulhce.

Refering to Fig. '1 the yoke or l" ail conr prises a transverse member and depend ing side arms 15 and 15*, the former hata a. cam finger 15 and a hook 15 in rear th of. The associated pawl 10 has a forwardly extending arm 10 with a laterally turned portion 10 to engage the hook l5 and an upwardly and forwardly extending branch with a stud 1O to ride upon the can fin er 15 Normally this stud engages th gh part of the cam finger as shown in thereby holding the latch yoke no rearward. W hen the pawl is swu said stud passes into a recessed the side arm l5" above the cam yoke drops so that its hook 15 becomes Vngaged with portion 10 of the pawl shown in Figs. 3 and 5.

The parts above referred to as latch yokes or hails form parts of the couplings where by the tripping of one pawl 10 (as hereinafter described) results in the tripping oi": other pawls to the right up to the point oi" split, and the coi'lstruction here shown provides for establishing the split between any two adjacent numerical orders. lit will he spring strip 17R that or yoke will pawl. so to unlatch the assotyne-carrying lever and p rmit it to l. e of its usual movements including o step advance -for setting up a cipher er than this the i are con so that one wil an i ie t right 1 i i Then th piece #5 econ o the right, a -.i--

From this it will be clear that the forward position of the Various finger pieces is the normal one, the intermediate position is the splitting one and the real-most position is one which results in the preventing of the p 'inting of a total. In order to make certain the three conditions of these adjustable slides, each one has a stud 17 (Fig. 5) for engaging the ileprcssions'oi a spring detaining strip 17-.

l ach oi" the coupler pieces 16 is drawn forward to cfiective position by a spiral spring 16 which connects an ear oi" the longer arm to the transverse portion 15 of the yoke, as clearly illustrated in Fig. 7. and when the associated slide 17 is moved rearward and its lip 17 acts upon the coin pier piece, the latter is swung upon its pivot in opposition to the spring, though this spring oi r-ogii-se is not strong enough to dislodgethe stud 17 from the notch of the Assuming one or more of have been thrust rearward to e position and the associated thus forced rearward out t the adjacent latch yoke, e obvious that tripping of one latch yoxe oy another will cease with the tripping of the yoke carrying the displaced coupler the -t follows that the pawl of ical order to the right will i see,

iliis end the left side piece i latch yolie extends (lo.vn\\a1'dl} p e wh h is operated upon in Way by the amount key liell cranks will he understood that here, as in Burroughs machine, the depresrmount liQW results in rearw rd c i slide strips W' on rrwarci to establish machine, the red swing the pawls it and 4% latch yoke-s brings the forward f e extensions or the'side pieces p to shoulders 21% as illustrated 1s. 5. Therefore-rearward movee, of a slide strip as caused by depres sion an amount key results in swinging the associated latch yoke rearward and disgaging its hook 15 from the pawl so that tile latter swings rearward releasing the type "carrying leve The coupler piece 16 acting;- upon the ear 1. of the adjacent latch yoke to the right swings that yoke rearward, also releasing the next pawl and type carrying lever, and this action continues until the yoke is reached whose coupler piece has been displaced by the rearward setting of ih 'ilie studs 10, for necessarily rearward swinging ofthc yokes by the detent strips 2H lged with tlie associated type cara shoulder 21% on the detent must be sufficient in extent to unlatch the pawls. However if the pawls did notthen serve to furtherrctract the yokesand hold them back (as they dothrough coaction of the studs 10 and cam fingers 15) the yokes would swingforward to some extent when movement of the slide strips fidywhenever amount keys depressed and when those stri s were restored to normal in the successive itemizing operations of the machine. fduch unnecessary vibration of yokes obvlatcd by extreme retraction eiiected through action of the studs 10* upon the cam fingers 15 whereby the yoke arms l are carried. out of reach ofthe shoulders 21% of the slide strips 21% and so held.

Referring to the matter of transferring or carrying tens, which in a machine of the character here shown comes about as a re sult of onestep up vard movement of racks 6 .0 (pl iissible by reason of the same connection between these racks and the lovers that provides esthe one-step advance of the latter to set up ciphersyp-special provision is made for preventing any interference with the transfer action on account of the presence of the pawls which, if engaged with the levers though not obstructing the actual transferring rise or" the rack, would prevent restoration of the transferring racks to normal. Thus, in addition to a release of pawls 10 through depression oi the amount keys, they may be released through the rise of racks 610 in effecting transfers. it will be understood. in this connection that when establishing one or more splits in the ordinary uses of an adding machine it is customary to provide leeway ior accumulation of totals one or more orders beyond the highest order of the dillerent divisions into which the machine has been split. in carrying out my invention l: have provided a special device for releasing the type carrying lever of a higher order into which a total may be extended. whenever the rack of such order rises to effect the transfer or carry. Thus I pivot upon the key-stop guide-plates 210 a series of similar bell cranks, a descrip tion of one of which willsuflice for all. it comprises a forwardly extending" arm 22 .lgs. E2 8, 5, and 8) having a laterally turned end portion extending through a slot Ell in one of said guide plates so as to be struck by the rack when the latter rises to effect a transfer; and an upwardly projecting arm 22 which has a laterally turned portion extending in front of a branch of the left side piece of the associated latch bail. The two arms 22 and 22* are united by a transverse portion 22 which works between stop shoulders on one of the plates 210 (Fig. 5) whereby the movement of the bell crank is limited. It will be obvious from the above that when the rack rises and rocks tbebellcranlz, the latter (will displace tie latch yoke and thereby release the asso ciated pawl 10, so that in the next operation of the machine the associated type carrying lever may move downward one step and re store the rack to the normal position, in which it is held by the usual transfer pawl. Referring to the matter of restoring the machine to a normalposition it will be understood that in a series of operations under a split adjustment, some of the type carrlers may remain latched, and in fact this is likely to be the case since ample provision is usually made for extending the totals and so certain type carriers may not be unlatched even as a result of carrying or transfor operations. I provide for the unlatching of any such type carriers by the act 01? throwing forward the handle lei. The disks 13 are formed with upper branches 13 having laterally turned end portions adapted to act upon the rear arms 24% of levers journal ed on the cross rod 200 and having forwardly projecting'arms 2 underlying the laterally turned portions of the coupler pieces l6-to wit, the ears to which the springs 16 are attached (Fig. 7 When the arm 14 is thrown forward the laterally turned portions of the disk-arms 13, rock said levers so that their forward arms acting upwardly against said ears of the coupler pieces will rock the latches rear-- ward and release any of the pawls 10 that have not therefore been released, and so release associated type carrying levers. The levers Qt-Qal also have upwardly projecting arms 24%? which play a part presently to be described in connection with the subject of preventing printing of totals in certain orders. I

' Referring next to the matter of totaling operations, (see Figs. 1, l 1 it will be understood that the totaling system is the familiar one employed in Burroughs ma chines. The numerals 265 and 265 designate respectively the total and subtotal keys which operate through familiar connections to so affect the accumulator controlling devices as to either keep the pinions.

916 in mesh with the racks 610 during the descent of the latter and disengaged during their ascent, or engaged during both descent and ascent. Now since it might very Well be that split Work was to go on after striking of totals or sub-totals, l make provision for automatically relatching all of the pawls 10 in their forward positions at the conclusion of an operation of the machine for the taking of a total or subtotal. The total key bell crank lever 22'? is as usual connected by the link 22? to an arm 1400 secured to the rock shaft 1400 l mount loosely upon this rock shaft a bail composed of side arms 30, connecting tie: plates 3O (Figs. 1,.2.aml 9) and an outer cross rod adapted, upon the forward you:

Obviously the above described resetting operation is advantageous in case a difierent '1 subdivision of the machine is called for by the character or" work to be handled follow lug the cleuring of the eccun'iula'tor at the conclusion of the preceding work which has terminated with n. total printing oporatioi'l leaving the accumulator clear. The resetting is useful also where work is to con tinue under the some split adjustment as before because it will here-the-effect of preventing the printing of any" ciphers to the left of items-heading the new Work. This might otherwise occur by reason of the release of typecurrying levers as a result of transfer or carrying operations. Thus in the event of a typecarrying lever in an order higher than those wherein amount keys have been. operated, having been released through advance of its'rack to efiect a carry, that type carrier would still be unlutched and therefore when the first itelnizing was done after the totaling operation, e cipher would be printed to the left of the item and of course the extent to which accumulating had gone might be such as to cause the printlhis would be obing oi several ciphe ectionebie on account of the confusion it at the head of a list and would course be prevented by the relctclnng of all of'tbe type carriers us aresuit of the preceding total printing opera- 4, p i tlon of its spring 36 to'the pos tlon shown in l a L/ \1 tion. Such printing of ciphers as a result of carrying operations may occur during the listing of items but other items in the same column printed without any ciphers tothe left will serve to obviate any confusion as to 10: the line of split or subdivision. Then the fact that type carriers which are unlatched as result of transfer of carrying operations, remain unlatched untii totaling operation has been performed is important for the reathat when comes to printing the total these particular racks must free to descend dis ances rrnined by backward rotation intermcshing accumulating Wheels F b fifiln'lOfG, the appearance of a to ieft of the highest digit of an 313?-S81"6 a. useful purpose because of the re met that it comes about as a resuit 0 e -rr ing operation. Thus it serves cation that there has been registration beyond the capacity of the Wheels be longing "to those orders wherein keys are in use, and therefore something in the nature of s warning to the operator against contiz-iuing to add items in one section of the accumuietor to the point of affecting the c'tion in the next adjacent section- 1:

asset and the machine operated? l condition, such. action will have the pawls in effective to the reason that the controlling yolites are held up by the levers 2t,

. to the matter ct eliminating imprints, each of the slides l? is movable to a third position correspondin ivi 1 the inscription l lo total upon the plate 15, and when so moved will establish connections whereby depression oi the total or sub-to al hey will latch up the associated type car er preventing movementthereot to set up 1 pc for the total. To this end each of the slides 1? has at the rear a laterally turned foot 1'? (Fig. 4:) adapted, when the slide is moved to its extreme rearward position operate upon a lever carried by an arm 19 fastened to the rock shalt 20st to which the total key bell crank lever 22? is secured. There is one the arms 19 for each slide it (see 8) and it will be obthat whenever the total or subtotal hey is depressed this series of arms will be swung downward. Normally the levers carried by said arms respectively are held ton as to their upper ends and rearward as thei" lower ends by springs 20 con necting; their lower ends with the arms l9 53'} so that these levers pass to the rear aterally turned portions 10 of the v extending arms of the pawls 10. However, when any slide 17 is moved to the third position, the associated lever 21) is rocked to the position shown in Fig. l wherein, lower end overlies the laterally extending portion 10 of the associated. pawl Then when the total hey is depressed and the arms 19 swung downward all pawls 18 cl or are where slides l? have been moved the positi n will be swung forward will hold up associated type carrying levers Unless these levers move from n position there will of course be no in those orders when machine with the total hey depress-ed l" fion pawls 3.0 are not latched ,c ve position as it would not be desirable to con one the condition beyond the single totaling" operation. Therefore the slides 12 besides acting to set the levers 20 in the manner already described. act also when moved to their extreme rearward po 13.. .1. .l.l salon, so rock the levers Si l. For this purpose the slides are equipped with studs Q6 adapts to act upon the'upscandinh; arms-2t" oi? levers 2t and rock the same illusoli to trated Mg. so as to hold the a. 028} 1'0 and prevent latching the p ate it winch are swu J i the division wherein s forward and the la ch bails or the total imprint is to be eliminated. This thrusting rearward of the group of slides is not only a matter of simple manipulation but has the advantage of showing at a glance the extent of the division of the machine wherein the printing is prevented,

Referring again to the automatic action of the latch yokes when permitted to swing down by reason of the pawl studs 10 riding ed the cam fingers if and into the recessedlatch yoke to latching position,'and other latch yokes to the left will be similarly affected by reason of engagement between thelaterally turned ears 15 of successive latch yokes and shoulders 16*- of neighboring coupleis 16. As to an extreme right hand division of latch yokes which of course would not be adected by the setting of a slide 17, a special spring is provided (see Fig. 8), which spring connects the extreme right hand latch yoke with a fixed stud 25. This spring streets the yokes throughout the entire series when the handle 14 is thrown forward and no slides 17 have been moved rearward so that whetheror not one or more slides have been set for splits before the handle it is swung forward to put the machine in splitting condition, there will be some spring" tension tending to engage the latch yokes with the pawls and acting in aid of the gravity ofthe latch yokes whereby to insure a latching of the pawls in their forward positions. The spring pressure however is so light in any case as to add no apreciable resistance to depression of amount eye when this is to result in displacement oi latch yolzes.

It will be seen that the above described construction is well calculated to carry out the object primarily Stated but it must be understood that this construction is susceptible of considerable modification within the scope of my invention. An advantage of the latter as compared with those forms of splitting means which involve special constructions'of printing or impression controlling mechanism, is that I am able to locate the handles of my splitting structure at the trout of the machine whereqatkey Ban be most conveniently manipulated and where they most readily indicate conditions as to denominational division, while at the same the interior splitting mechanism is closely adjacent so that short and direct connections (as be made, whereasthe printing mechanism is usually remote. from the front its of tie keyboard of these machines and in "case oflocation of splitting handles or keys there, when the interior splitting mechanism 18 mcorporated m the printing department of the machine, long and indirect operating connections are necessary and there are 2.
